Abstract: Autothermal Reforming and Processes Utilizing the Same. 
     The technical field of the invention concerns the production from hydrocarbonaceous feeds of hydrogen-rich gases and use of the same in various synthesis operations. An autothermal reforming process, as illustrated in Figure 2 of the drawings, comprises carrying out partial oxidation of a hydrocarbonaceous feed by introducing an oxidant gas (e.g., air), steam and hydrocarbonaceous feed (e.g., a hydrocarbon) into an apparatus (24), as illustrated in detail in Figure 3, which contains a catalytic partial oxidation section (24a). A monolithic catalyst (27) comprising palladium and platinum and, optionally, rhodium, distended upon a stabilized alumina wash-coat is contained within section (24a). At least one half by weight of the hydrocarbonaceous feed is catalytically oxidized in section (24a) at a high throughput rate to produce a heated effluent suitable for further processing, such as being passed through a steam reforming catalyst (31) contained in section (24b) of apparatus (24). The hydrogen-rich gas thus obtained may be used as is or further processed for use as a synthesis gas for methanol or ammonia synthesis, or for the synthesis of normally liquid hydrocarbons or synthetic natural gas.

Abstract: A galvano-plastically produced graduation carrier comprising fine perforations located within a perforation zone wherein stability enhancement regions in the form of prominences and depressions in the embodiment are located outside the perforation zone. The stability enhancement regions enhance the ability of the graduation carrier to be self-supporting. The area of the graduation carrier within the perforation zone can therefore be made thinner than other areas of the graduation carrier. This provides a graduation carrier which not only has improved edge sharpness and fineness of the perforations but also a high bending rigidity and improved handleability.

Abstract: in a binarizing system in which analog picture image signals formed by scanning a manuscript with a line sensor undergo quantization and digital picture image signals obtained by the quantization are binarized into signals representing black or white according to a predetermined threshold value, levels of a digital picture image signal of a picture element to be corrected and of a digital picture image signal of a picture element at least one main scanning line before the picture element to be corrected and positioned at the same position as the picture element to be corrected in an auxiliary scanning direction which is attenuated with each main scanning line or lines are compared. Among the above two signals, a signal having a larger level at a given time is used as a reference signal showing the nature of tone of the manuscript. When the level of digital picture image signal of the picture element to be corrected is smaller than the level of the reference signal, the level of the digital picture image signal is decreased. In other cases, the level of the digital picture image signals is maintained. By this operation, the nature of tone of the manuscript is emphasized. Thus, accuracy of judgement in binarizing analog picture image signals is improved. Figure 6.

Abstract: @ A technique for improving efficiency of error-correction coding is disclosed for use in a Gray-coded multilevel transmission system and, specifically, in a quadrature amplitude modulation (QAM) transmission system. To this end, information bits in information bit symbols are converted, i.e., mapped, (via 104 and 105) (208 and 207) into error-correction bit symbols having fewer bits than the corresponding information bit symbols. This bit-converting technique permits use of encoders (106) and decoders (209) having a code rate lower than the overall transmission code rate. (FIGS, 1 and 2)

Abstract: The liquid chromatograph comprises a multiple piston pump (1) which is arranged so that the delivery strokes of two pistons overlap to such an extent that for all designed liquid delivery pressures and compressibilities no period exists when no piston is delivering liquid. Thus for all other than worst case conditions there are periods in each pump cycle when two pistons are delivering liquid. The start of these periods is detected by the pressure increase produced at the outlet of the pump and measured by a pressure transducer (5). The output of the pressure transducer is fed via path (14) to a motor drive circuit (10) which controls a motor (4) which drives the pump (1) via a shaft (3) so that the speed of advance of the pistons is halved until one of the pistons ceases delivery. Consequently a relatively pulse free liquid flow is produced by the pump with a relatively simple motor speed control sustem.

Abstract: In a system in which a main processing device (1) executes an interrupt process having a high processing priority, the processing priority of each interrupt generating source (75-7n), is registered in a table (72). An intermediate processing device (71) receives an interrupt signal from each interrupt generating source (75-7n), obtains the corresponding process priority from the table (72) and then informs the main processing device (1) of the interruption. Accordingly, the process priority of the sources (75-7n) can be easily changed, and the system has a small size because the interrupt circuit for the main processing device (1) is centralized.

Abstract: A modem system is disclosed which has improved reli­ability of detection of transmitted PSK data using a simple signal delay detection scheme. A transmission signal is produced in which repetitive digital time slots each contain phase encoded "mark" or "space" data. Each time slot includes a reference phase portion at at least one of a front and rear portion of the time slot. The phase of the transmitted signal changes in the remaining portion of each time slot in accordance with applied digital data. For a "mark" data signal the phase changes from a reference phase in a first direction to predetermined phase in a first half of the remaining portion of the time slot, and then back to the reference phase before the end of the time slot. For a "space" data signal the phase changes from the reference value in a second direction opposite the first to another predetermined value in a first half of the remaining portion of the time slot, and then back to the reference phase before the end of the time slot. A simple delay detection demodulation system is used to recreate the original digital signal.
